No other damage was caused in the incident, which occured last month. Samsung has agreed to replace the phone.

More recently, Swiss teenager Fanny Schlatter was shocked when her Galaxy S3 caught fire in her pocket -- the melted phone pictured above -- leaving her with second- and third-degree burns on her thigh, according to L'Essentiel.

Chinese woman electrocuted

And in a separate tragic incident, 23-year-old flight attendant Ma Ailun was electrocuted in her Xingiang home while answering her iPhone 5 after getting out of the bath, Reuters reports. She was due to marry next month.

Ma Ailun's family say the phone and accessories were bought in an official Apple Store. Apple says it will investigate the incident.

A shock of 36V can kill, but mobile phones alone can't generate anything like that kind of level. A damaged charger can -- like any damaged electrical device -- produce a shock though. We're pretty fond of you guys, so don't handle your gadgets with wet hands, keep an eye out for damage, and don't forget to insure your stuff.

Stories of phones exploding or catching fire have been with us since phones first met pockets, but it's worth pointing out they're not always what they seem. Sometimes people just don't want to hold their hands up and say, "Yup, I put my phone in the microwave."
